Abstract: 1,176,067. Photo-electric circuit. SQUARE D. CO. Aug.24, 1967 [Dec. 15, 1966], No.38944/67. Heading G1A. A control circuit in a hazardous area, where an explosive atmosphere may be present, is monitored by circuitry which is located in a non- hazardous area and which comprises one part supplying a small current, insufficient to ignite the atmosphere, to the control circuit which is linked via a radiation path to another part supplying heavy current to a controlled device thereby avoiding heavy current from ever reaching the explosive atmosphere and igniting it. In the drawing a lamp 82 is in series with a silicon controlled rectifier 90 which conducts with closure of the control circuit contact 62 in the hazardous area 12. Light from the lamp is received by a photo-resistor in the heavy current part of the circuit 18 to bring up relay 48 and operate a load 38. The opening of contact 63 in the hazardous area switches off the silicon controlled rectifier 90 to extinguish the lamp and release the relay.

Title: Rolling ceramic materials in a plastic condition
IPC: B28B3/12
Filed: 1969-08-05
Abstract: 1,216,027. Rolling ceramic material. FETOK G.m.b.H. 5 Aug., 1969 [6 Aug., 19681, No. 39044/69. Heading B5A. Ceramic material is roller sheeted between a pair of rolls one of which is connected to the positive terminal of an electrical source and the other of which is connected to the negative terminal. During rolling a current flows from the positive roll through the ceramic to the negative roll, which current is thought to cause the water within the ceramic material to migrate to the negative roll to form a film thereon at the point where the rolled sheets leave the roll. This decreases the friction at the point of release and thus facilitates the release. Also since the water adheres to the sheet rather than the roll the major part of the region and of the roll which contacts the material to be rolled is dry and an increased friction between the sheet and the roll is facilitated, which increase is advantageous in feeding the material through the roll gap and allows rollers of decreased size to be used. Moreover the rolled sheets produced by this process are said to have increased resistance to bending both in the dry and fired states.

Patent GB-847854-A (GB)
Title: Vacuum method of refining steel
IPC: C21C7/10
Filed: 1957-12-18
Abstract: A vacuum process of refining iron in a furnace covered by a layer of slag comprises raising portions of the melt into a vacuum vessel and returning them to the melt.  The portions may be raised by varying the pressure within the vacuum vessel by the introduction of an inert gas, or alternatively, the vessel itself may be raised or lowered. Due to the reaction between FeO in the slag and carbon in the melt being favoured by vacuum, alloying additions of high C content may be used when producing low C steels.  Ores or alloying additions may be added in the vacuum vessel, and due to the reducing action of the metal with extremely low carbon content very low FeO content slags are produced.  The invention is suitable for use in combination with Heroult or open hearth furnaces which may be provided with an oxygen blast on to the slag surface.  Specifications 801,518 and 836,260 are referred to.

Abstract: 884,654. Sewing machines. SINGER MANUFACTURING CO. Dec. 17, 1957 [Jan. 14, 1957], No. 39871/60. Divided out of 884,653. Class 112 A sewing machine comprises a rotary bobbinreceiving spindle disposed at right angles to a planar surface on the machine casing, a threadguiding stud or sleeve formed at an end in engagement with said surface in a plane at an angle to the axis of the stud or sleeve, whereby the latter may be rotated for varying the inclination of a longitudinal line on the periphery thereof relatively to the axis of said spindle, and means for securing said stud or sleeve in adjusted position on said surface. The stud or sleeve thereby serves to control the lead of the thread to a bobbin to obtain even winding of the latter. Thread is led from a spool 9, mounted on a spindle 8, to a thread-guide 20 situated at the front of the machine arm 4, and from thence along the front of the arm over an adjustable guide 21 to a bobbin 16 carried by the rotary spindle 13 of a bobbin winder assembly as described in Specification 884,653. The guide 21 comprises a sleeve 22 secured by a screw 23 to a surface 28 which is normal to the axis of spindle 13. Screw 23 passes through an enlarged bore 24 and its head 25 seats in a counterbore 26. The lower surface 27 of sleeve 22 is at an angle to the axis of the sleeve. In a modification screw 23 fits closely in a bore which is skewed relatively to the axis of the sleeve. The latter in either case may be rotated and secured in adjusted position by the screw.

IPC: B24B3/24
Filed: 1958-12-11
Abstract: 932,422. Grinding twist-drills. BIRMINGHAM SMALL ARMS CO. Ltd. Dec. 11, 1959 [Dec. 11, 1958], No. 39923/58. Class 60. The flanks 29, Fig. 5, of the point of a drill are ground by moving each flank in turn across the annular portion 31 of a cupped wheel 1, Fig. 2, the direction of movement being inclined to the wheel axis so that each flank is ground to final form as it moves across the inner edge of the annular surface of the wheel. The wheel 1 is driven by a motor 2 adjustably mounted on a table 4 to allow for wear of the wheel, and the drill support assembly comprises an arm 3, Fig. 1, pivotally attached at 19 to a plate 17 which is itself adjustably inclinable to the plane of the slide 14 to which the plate is secured by clamps 18. The slide may be moved by an operating handle 15 along guide rails 12, 13 on a carriage 8 which is hinged at 9 to the base plate 6 and has an adjusting screw 11 at its opposite end to raise or lower that end relative to the base 6 which is also adjustable, attached to the table 4. Angle scales may be used for setting the various adjustable members. The drill is supported on the arm 3 by a V-block 30 and, adjacent the point, by an abutment 26, Fig. 5, having a point 27 which contacts the surface of a locating bar 25 which engages a land of the drill. The abutment is adjusted to engage the edges of a flute of the drill close to the tip and is secured by a bolt 28, the lip of the flank 29, these being substantially horizontal. After adjustments to the mounting assembly have been made to provide the desired point profile the drill is secured by a screw 23 at its butt end, finger pressure being sufficient to retain it in position during grinding, which is effected by moving the slide 14 down the carriage 8 so that the flank to be ground moves across the face 31 of the wheel in the direction F, Fig. 2, until it reaches the position a below the wheel axis, the ground flank then having cleared the grinding surface. After each traverse the screw 23 is adjusted to increase the cut. The adjustments provided affect the shape of the point as follows: movement of the base plate 6 about its axis perpendicular to the table 4 affects the curvature of the elliptical surface of the flank, rotation of the plate 17 on the slide 14 regulates the clearance angle at the lip, and swinging of the arm 3 about its pivot 19 determines the point angle. The screw 11 is used in conjunction with the axial adjustment of the motor 2 to position the drill relative to the wheel; the axes of the various adjustments are centred, as near as practicable, on the point a of the wheel.

Title: Code conversion of messages
IPC: H03M5/00
Filed: 1973-08-23
Abstract: 1439989 Selective signalling PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 23 Aug 1973 [26 Aug 1972] 39931/73 Heading G4H [Also in Division H4] A code word of a second (palindrome) code consists of 2n-1 or 2n elements (e.g. bits) the first n elements of which consist of the n elements of a word of a first code in the same sequence and the last n elements of which consist of the same n elements in reverse sequence. The address of a paging receiver in the first code is stored in a first register and converted into the second code before repetitive transmission by radio to the receiver to make a sync. word unnecessary. The conversion is done by connections from the first register to a recirculating shift register large enough to hold the whole word of the second code, e.g. the first stage of the first register is connected to the first and last stages of the second register. Alternatively the bits are gated from the stages of the first register by AND gates (one per stage) enabled by a decoder in turn. Alternatively, the conversion is done using a loop shift register large enough to hold the word in the first code, which after loading, is shifted with successive revolutions being in opposite directions. In a paging receiver, the code word is entered into a shift register and recognized by a gate connected to all the register stages and feeding an integrator which controls a visual or audible alarm via a threshold device. If the (repeated) code word can be recognized at more than one position during shift-in, the threshold can be adjusted correspondingly, or each output of the gate may start a clock-driven counter which blocks further outputs from reaching the integrator for a period. The length of the shift register can be (about) halved by using two gates to recognize the two "halves" of the word, the output of one gate being ANDed with the delayed output of the other. The delay may be achieved using a shift register or counter or clock-driven counter. This clock-driven counter performs the delay and the function of the other clock-driven counter mentioned above. One or more bits in the middle of the word in the second code may represent variable information as distinct from the receiver address, indeed the whole word may do so. A final receiver embodiment uses a 19- bit word in the second code, all but the middle 5 bits being the receiver address. With the word in a 19-bit shift register, a gate recognizes the address in response to all but the middle 5 stages and provided, in addition, the middle 5 bits satisfy the palindrome condition, a pulse is supplied to an integrator which controls an audible or visual alarm via a threshold device. The pulse also gates the 3 non-redundant bits of the middle 5 bits to means which decode and possibly display the variable information therein. Display may be blocked if the threshold device does not produce an output. The code elements above are bits (binary) but may alternatively be ternary or other multivalent. Transmission may use bipolar signals, or 01 for 0 and 10 for 1.

To facilitate the loading of a tape 2 around a drum 1, the tape being normally guided on and off the drum by guide members 4 and 5 held rigidly parallel by a frame 6, the frame is pivotally mounted by two coaxial shafts 7 and 8 on two forks 9 and 10 of a mount 11 which is slidable away from the drum along guides 12 and 13. When the tape is loaded, the guide assembly is moved towards and located relatively to the drum by conical pins 14, 15 projecting radially from the drum to wedge between guide members 4, 5. Fine adjustment of the operative position of the guide assembly is made by radially adjusting the protrusion of the pins 14, 15 and by mounting the pin 15 on an eccentrically adjustable holder. The frame 6 includes an additional guide member (Figs. 2, 3, not shown) to keep the incoming and outgoing tape bights apart. Resilient means on the mounting 11 (Figs. 4, 5, not shown) limit the endwise excursions of the rods 7, 8 and a peg-and-socket arrangement (Fig. 5, not shown) limits other movements of the frame 6 during loading to an extent within the recovery of the operative position by the pins 14, 15.

Abstract: 1,144,520. Detecting knots in yarns S. PEYER. 1 Sept., 1967 [6 Sept. 1966], No. 40168/67. Heading D1F. In a device for indicating and/or recording the occurrence of knots in a travelling strand such as a yarn or cord and perhaps for arresting yarn travel or the machine in which yarn is being processed, deflection of a ferromagnetic member from a sensing position normally maintained by a permanent magnet field causes a change in the field which induces current surges or pulses in an inducton coil magnetically coupled therewith. In the device shown, yarn 6 passes through a gap 38 adjustably formed between a cylindrical stop member 22, which is eccentrically mounted on and secured to a fixed pin 20, and a U-shaped sensing bow 36, pivotable between stops 46 about the axis of captive ends in a groove 30 in a cylindrical member 28 but normally maintained in the position shown by the bevelled edge of an iron core 42, a part of which is surrounded by a permanent magnet 40. The passage of a knot 8 deflects member 36 and the resultant change in flux linkage induces in a coil 44 current surges which, or preferably only the surge due to the restoring movement of member 36, are amplified at 50 and recorded on a counter 52 and/or operate a relay 54 to initiate a stopmotion (not shown).
